The blower motor relay in a 2005 Chevy Astro van acts as a switch that controls the power supply to the blower motor, which is responsible for circulating air through the vehicle's heating and air conditioning system. When the ignition is turned on and the climate control system is activated, the relay receives a signal and allows electrical current to flow to the blower motor. If the relay fails, the blower motor may not operate, leading to a lack of airflow inside the cabin. Essentially, the relay ensures the blower motor functions properly based on the driver's settings.
under the hood on the passenger above the blower motor mounted to a bracket.
the blower motor relay is located next to the blower motor it is connected to the motor by a purple and black wires
fuse? switch? Selector?
Check your blower motor relay!
The blower motor relay only operates the high speed function. That relay would be in the fuse/relay center under the hood.
on right front side of eng compartment
The blower motor relay for high speed would be located in the power distribution box under the hood.
Not knowing what year S10 you have, you can generally find the blower motor high speed relay nearby the blower motor on the firewall. The resister for the other lower speeds is also found close by the blower motor.
The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
There is a fuse for the blower motor on the fuse panel, I do not know of a relay.
Swap the relay with a known good one, many of the relays are of the same part number. Keep in mind that the blower motor relay only controls the high speed function. The blower motor speed resistor and the blower motor switch controls the lower speeds.
Need to know what year. FYI, the relay for the blower motor only operates the high speed function. The lower speeds are operated by means of the blower motor speed resistor.
